o'r'ro E. SZEKELY, 0F MOLINE, ILLINOIS, AssIeNoR 'ro DAVENPORT- nooolvrorrvn WORKS, OF DAVENPORT, IOWA, A CORPORATION OF IOWA.

LOCOMOTIVE.

T 0 all whom it may concern:

Be it known that I, O'r'ro E. SZEKELY, a citizen of the United States, and a resident of Moline, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Locomotives, of which the following .is a specification.

This invent-ion relates to improvements in locomotives of the type and character disclosed in a prior application fon Letters Patent, Serial Number 583,198. filed on August 21, 1922 in the United States Patent Oiiice, namely; internal combustion motor driven locomotive, designed for industrial and construction work.

The object of this invention is to provide an improved truck and journal construction for locomotives of the general character hereinabove described and more especially the locomotive of said prior application.

A further object of the invention is to provide a method of jqurnal construction calculated to afford an improved mounting of the wheel journals in the truck frame including increased guiding area in the rela tive vertical movement between the parts, and other mechanical advantages having to do with the resistance to thrust and other forces to which the driving parts are subjected.

In the drawings a general disclosure of the locomotive is made, together with a more detailed drawing of the parts embodying the invention.

Figure 1 is a. general view in side elevation of the locomotive embodying the invention,

Figure 2 is an enlarged View in horizontal section through the journal box and drive as taken on line 2+2 of Fig. 1,

Figure 3 is an enlarged detail view of the journal box assembly as taken on line 33 of Figure 2,

Figure 4 is a view in end elevation of the journal box, and t Figure 5 is a perspective view of the journal box removed and parts disassembled.

Considering the locomotive in its general Application filed October 6, 1923. Serial No. 666,873.

aspects, it comprises amain frame 1, rigid throughout and symmetrical in shape. The frame is supported upon two pairs of wheels 2 located midway between the front and rear ends'of the frame, said wheels being journalled in journal boxes 3 which in turn are supported between vertical guides in the frame to afford relative movement therebetwecu. Springs 4-4 form the connection between the journal boxes and the locomotive frame. i Mounted upon the frame. 1, is a. heavy duty internal combustion motor 5 and occupying the forward portion thereof. A hood or housing 6 covers the motor. At the extreme front end is a radiator'7, similar in construction and function to the radiator of an automobile. The rear portion of the frame is occupied by the operators cab 8, which is journalled to the rear end of the hood 6.

Rearwardly of the motor 5, and coupled thereto is a transmission casing 9 with clutch and fly wheel housing 10 interposed between. The rear port-ion of the transmission casing extends into the cab. with the several operating levers at hand. namely,

a reversing lever 11, a gear shifting or change speed lever 12, and a clutch pedal 13, all within reach of the locomotive driver.

It will suffice to describe the locomotive power plant as conforming generally to a standard automotive practice, although owing to the essential differences between locomotive and road vehicle operation, certain departures are incorporated in the transmission mechanism which may be briefly referred to since they are fully described elsewhere. c

Inasmuch as a locomotive'is called upon to push as well as pull its load, and from either end, it must be capable of delivering thesa-me power atthe wheels regardless of the direction of travel, hence a reversing mechanism is introduced between the change speed gearing and the clutch to the end that equal power is delivered to the change speed mechanism in either direction; of rotation of the moving parts.

The power is ultimately delivered to the ing' 9 in axial: alignment with the wheel axles. It is to be observed that the trans mission casing is extended downwardly between the wheel journal in the form of rounded extensions 9 from which extend the axle drive shafts 14, 14.

Having consideredbriefly the drive from motor to the drive shafts 14, 14, the construction of these shafts,-journal boxes, and spring suspension will now be discussed.

In general, it may be said that the drive from the shafts 14-14 to the wheels is through a form of universal joint, which permits the free movement of the wheel journals with respect to the transmission casing 4. As shown in Figure 2, each wheel 2 is keyed upon a journal sleeve 15, which in turn is journalled at its endsin inner and outer bearing boxes 16 and 17, through the medium of roller bearings 18, 18, said bearing boxes forming apart of the complete journal box 8, supported by the frame 1 and adapted for movement in vertical guideways.

As clearly shown'in Figure 2, the frame member 1 is made up of a pair of laterally spaced and parallel side frame members 20-20, between which the journal box and wheel are mounted, said'frame members being provided'with openings 20, with wide slots extending to their lower edges, as

shown in Figure 1, toprovide for mounting of the journal boxes. On the opposed vertical edges of the vertical slotsin side plates 20, 20 are formed squared guide flanges 21, 21, which have bearing engagement and vertical sliding contact with the main journal member or yoke 22, which lies between the side plates and is extended laterally to completely surround the wheel.

Considering the structure of the journal box more in detail, the formation of the yoke. 22 is clearly'shown in Figure 5, as

consisting of a boxlike casting, open at top and bottom, and, as before suggested, floats in the guideways of the'side frame members, under the action of the springs. The end portions 23-23 of the yoke are U-shaped, one side being preferably reduced in height,

that is, upperedge of the yoke in extends only part way from the order to allow clearance for the brakes. The end portions -means of cap screws 28,

- an internal seat for the outer end'of ance against narv ournal structure is sub ected to.

unite at the central portion of the yoke in bearing blocks 24, 24 of increased thickness located near the top and extending downwardly a distance somewhat greater than one-half the height of the yoke. The under faces of the bearing blocks are semi-circular, and the space below entirely open to receive a removable bearing cap 25,'forming the under half of each bearing. Extending vertically on each side of the bearing blocks 25 are right angular bearing surfaces 26, 26 forming-the guide faces, which engage the guide flanges 21, 21 of the side plates.

The assembly of the journal box'is clearly shown in Figure 3, the bearing caps 25, 25

being bolted in position, after. the wheel 2, axle sleeve 15 and bearing boxes 16 and 17 have been assembled. A pair of cap screws 27, 27 extend upwardly through the bearing cap and are anchored in the upper half of each bearing block.

The bearing boxes 16 and17, are cylindric in shape, the inner box having the form of a flanged sleeve, in which is retained its roller bearing 18, and held in position by passing through the flange 29 thereof, and anchored in the face of the bearing blocks 24 and 25. outer bearing box 17, ismore in the nature ofa bearing retaining plate, fitting over the end of the axle sleeve 15,;and provided with socket in which the outer roller The bearing'18 is retained. The outer bearing,

box is flanged at 30 and a plurality of cap screws 31 anchors the same in place.

The springs 4, '4, are supported mediatetheir ends on the top faces journal boxes, by ing blocks 32, which are supported upon the healing blocks 24, 24, and on either side of the wheel. The free ends of the springs are connected to the frame 1 through the medium of shackles or other suitable means of connection.

It is 'tobe further noted that the wheel axle sleeve is broached to forma square thea-xle shaft 14,

' inter- .of the the latter being shaped partakes of the nature of an universal oint allowing for the movement of the journal boxes in' a vertical dlrection, aswell as any axial movement that may be present.

The advantage of this construction for means of spring support- 1;

in the form of a. head 14, generallysquarein cross 880131011,

journal box and wheel mounting resides primarily in the added strength and resiststrains and wear that the ordi- The journal yoke surrounding the wheel manifestly forms a rigid support for the journal bearings, insuring permanent alignment, and hence increased life of the running parts. Moreover the increased height and wide expanse of bearing faces throughout the vertical guideways, reduces the wear and distributes the thrust throughout a greater area, thus permitting a more rigid mounting of the Wheel.
